Method and system for positioning anchor point in augmented reality video picture

Abstract

The invention provides a method for positioning an anchor point in an augmented reality video picture, which is characterized by comprising a positioning module, a video terminal and a display terminal, the positioning module is connected with a video terminal and a display terminal. The positioning module comprises a video stream access module, a spatial position database, a spatial registrationand analysis module and a video image processing module. The method comprises the following steps: S1, determining an object needing to be calibrated in a video; S2, creating globally unique anchor point information of the object; S3, defining a display style of the anchor point object; S4, acquiring video terminal information and a plane coordinate of a to-be-anchored object; S5, analyzing and identifying the spatial position information of the anchor point object; S6, traversing the spatial positions of all the anchor point objects associated with the equipment ID; S7, judging whether the anchor point object is added into a to-be-rendered set or not; S8, traversing the anchor point objects in the to-be-rendered set, and analyzing the plane positions of the anchor point objects; S9, synthesizing and sending to a display terminal; and S10, enabling the display terminal to display the video picture.

Description

technical field [0001] The invention relates to the technical field of computer video and vision, in particular to a positioning method and system for an anchor point in an augmented reality video image. Background technique [0002] Augmented reality (augmented reality, AR) technology is an emerging technology that superimposes computer-generated virtual objects on the real world seen by users, which improves users' perception of the real world and helps us better understand the real world, and Interact better with the real world. With the development of AR technology, [0003] People have higher and higher requirements for displaying elements in videos, and the types of displaying elements are also becoming more and more diverse. How to ensure the accurate display of elements and avoid confusing display of information is a huge challenge for video space positioning. [0004] In video augmented reality scenarios, the superposition of elements in the screen needs to be sp...

AI Technical Summary

Problems solved by technology

Especially when the position of the anchor point changes due to movement, the information may not be displayed accurately, affecting the sense of reality and user experience

In addition, in order to ensure the calibration efficiency of the anchor point, in the existing AR display system, the information of the anchor point is usually stored in the terminal video acquisition device. When the terminal device is damaged, the anchor point will be lost, and the information display cannot be determined.
